I see you already found a solution but in the future you can buy Z-Wave remotes that mount to the wall like a light switch, but with no needed power. They usually have 4 buttons that can be programmed individually with something like SmartThings. Kasa plugs work with SmartThings so you could just set each button to toggle a specific switch. It can be a little slow sometimes, but it's worked for me.
